Application inea March 15, 1922.l serial no. Marzo. f

To all whom it may concern A Be it known that I, NATHANv Gane, a citii Zen ofthe United States, `residing at flewark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Sanitary Mouthpieces, of which the following is saecication.

Theobject of my said invention is the provision of a simple, practical and efficient sanitary mouth piece for telephones, speaking tubes and the like, the said mouth piece being characterized by aconstruction which permits of the disinfectant-carrying members being expeditiously and easily renewed when occasion demands.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a view showing my novel mouth piece partly in side elevation and partly broken away, as applied to ay telephone.

Figure 2 is a diametrical section of the improvement per se. v

Figure 3 is a detail side elevation showing the mouth piece member of the improvement.

Figure 4L is a transverse section taken through the complete device. Similar numerals of reference designate corresponding parts in all of the views of.

the drawings.

The mouth piece member of my lnovel mouth piece is designated by l. It maybe formed of any material compatible with its purpose, and includes a forward reduced and threadedl end portion 2, a rearwardly fiared portion 3 and a foraminous diaphragm 4l, the latter beingl spaced from the forward end of the member and arranged at the forward end of the flared portion 3,

as illustrated. Formed in the flared portion' Inaddition tothe mouth-piece member or body l characterized as described, lmyimprovement comprisesa jacket S of hard rubber, glass or any other appropriate material, and two annuli 9 of absorbent material surroundingthe `member l and 'seated in the before mentioned groove 6, and lde-` signed to be impregnated with a disinfect'- ing agent or with perfume as maybe deemed most expedient. The jacket 8 is provided at its forward end with an inwardly directed annular flange interiorly threaded as illustrated to engage thethread Z of the member l and thereby detachably secure the jacket 8 on the member l after the manner shown in v Figure 2.

It. will be manifest from thel foregoing that my novel mouth piece is adapted to be attached to and removed from a telephone member 11 inthe ordinary well known manner; also, that when the mouth piece as a whole is detached from the member 11,*the j y jacket S may be expeditiously and 4easily removed from the member l so as to permit of the annuli Qbeing provided with a fresh 'I supply of disinfectant or the like. also be manifest that the said annuli`9 can be conveniently immersedvin disinfectant,

as a handle forv the member l being used such purpose.

After the annuli 9 are supplied with dis-` `in the ordinary well known 'mannen In the practical use Aof novel mouth piece it will be understood that the fumes given off by the impregnated annuli 9 will occupy the annular space between the member l and the jacket 8 and will enter theA lt will 1 i member l through the apertures therein,

with the result that the mouth piece as a whole will be rendered sanitary vand not liable to transmit disease.

I have entered into a detailed description of the construction and relative arrange! ment'of the parts embraced in the present and preferred embodiment of my inventionin order to impart a full, clear and exact understanding of the said embodiment. `I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts inasmuch as in the future practice 'of the invention various changes and modifications roo may be made such as fall Within thel scope of my invention as defined in my appended claims Having described my invention, What l claim and desireto secure by Letters-Patent, is

l. A mouth piece for telephones, speaking tubes and the like comprising a mouth piece or body member adapted at its forward end or its detachable connection to a telephone or speaking tube and having a rearwardly flared portion and an exterior thread at the forward end thereof and also having a circular series of apertures in said portion at an intermediate point in the length thereof, and exterior grooves at opposite sides of said apertures, absorbent annuli arranged in lsaid grooves, and a removable jacket snugly receivingl the said mouth piece or body member and the annuli and having at its forward end an interiorly threaded flange engaging the thread on said mouth piece or body member.

2. A mouth piece or body member With apertures in its Wall and grooves in its outer side at opposite sides of said apertures, in combination with absorbent annuli in said grooves7 and a jacket surrounding said member and' annuli and detachably connected at its forward end to the member.

ln testimony whereof, I alli); my signature.
